BROODER.

Application filed October 23, 1924. Serial No. 745,327.

The invention relates to brooders, and more especially to the means for supplying heat thereto.

The object of the invention generally stated is to provide an oil burning apparatus for brooders having means of an advantageous construction for governing he height of the burner flame.

To the attainment ofthis object my apparatus comprises a stationary source of oil supply located to one side of the brooder proper, and a burner mounted beneath the brooder canopy torup and down movements relative to a constant oil level to control the height of the flame; and it further contemplates a link and lever structure of an advantageous character operable from a point to one side of the brooder canopy to raise and lower the burner beneath the canopy.

A general object is to provide a construction which is simple and compact in character, presents a neat appearance and in which the operating parts are entirely enclosed with the exception of an operating handle, 'so as to avoid injury to the chicks.

In the accompanying drawings Figure 1 is a vertical elevation section illustrating a brooder embodying my invention.

Fig. 2.is a transverse sectional view "taken approximately in the plane of line 22 of Fig. 1.

Fig. 3 is a vertical sectional view showing a detail of construction.

The brooder proper comprises a canopy 3 supported upon legs 4 a suitable distance above the ground. Beneath the canopy 3 is mounted an oil burner 5 of suitable construction and of the wickless blue flame type. Thus it comprises a burner bowl 6 mounted for up and down movements to vary its position and hence the height of the flame with respect to a constant oil level maintained in an oil Well 7 in constant communication with an oil supply tank 8 in a well known manner. Oil flows from the well 7 through a supply pipe connection to the burner bowl 6. Said pipe connection comprisesa pipe 9 depending from the oil well 7 and connected by a horizontal section 10 with a pipe 11 extending upwardly beneath the canopy of the burner bowl 6. A depending tubular stem 12 communicating at its upper end with the burner bowl depends therefrom into the pipe 11, the usual packing box 13 being provided to permit the stem 12 to slide up and down in th pipe 11.

The burner 5 and the supply tank 8 and associated parts are mounted at opposite ends of an elongated housing 14 formed of and the latter has air inlet openings 18 in its peripheralwall.

The oil well 7 and the reservoir 8 thereon are'supported upon the outer end of the housing 14 by a vertical enlargement 19 thereof having a top member 20 through which the pipe 9 passes. The reservoir 8 may be secured to the well 7 in any suitable way, as, for example, by means including members 21.

The means which I have provided for raising and lowering the burner relative to the constant oil level comprises an operating lever 22 pivoted at 23 on an upstanding plate 2 1 at the outer end of the housing 1 1 and operating through a slot 25 in the outer face of the auxiliary housing 19. I provide 1 a positive connection between this lever and the burner bowl, comprising a series of links and levers operating. upon a U-shaped bracket 26 slidably mounted upon the upright oil supply pipe 11 leading to the burner bowl. Said link and lever connection consists 'of a bell-crank lever 27 fulcrumed at 28 upon one end of the horizontal pipe 10 and connected to the inner end of the lever 22 by means of a link 29. The other arm of said lever is connected by a link 30 with a similar bellcrank 31 fulcrumed near the opposite end of the pipe 10 on a pivot 32. The other arm of this bell-crank 31 in turn is connected by a link 33 with a lever 34 fulcrumcd on a pin 35 which is carried by an upstanding bracket member 36. The opposite end of the lever 34 enters a slot 37 in the U- shaped bracket 26, and the latter is connected by a member or plate 38 with the under side of the burner bowl. The member 36 is secured at its upper end to the under side of the drip pan 15 and at its lower end to the bottom wall 39 of the housing 14.

the medium of the member 38 operating in a small slot in the drip pan. All of the operating parts it will be observed are enclosed with the exception of a portion of the lever 22, so that the apparatus presents a neat appearance and avoids any possibility of injury to the chicks. Moreover the construction is relatively simple so that it can be economically manufactured.

I claim as my invention:

1., A brooder having, in combination with a canopy, an oil burner having a burner bowl, a source of oil supply, a supply pipe connecting said source of oil supply with the burner bowl, the arrangement being such that the source of supply is located to one side of the canopy. said burner bowl being mounted for up and down movements, means for effecting such up and down movements includinga bracket vertically slidable on the oil supply pipe leading to the burner bowl, a lever for actuating said bracket to raise and lower it, and means for operating said lever from a position to one side of the can- 4 opy comprising a second lever and. a link and lever connection between said two levers whereby movements imparted to the second mentioned levervare transmitted to the first lever to raise and lower the burner bowl.

2. A brooder having, in combination with a canopy, an elongated housing having one means for raising and lowering the burner including an operating lever mounted on the outer end of the housing, a second lever mounted at the inner end of the housing beneath the burner and operatively connected therewith, and means enclosed within the housing for operatively connecting said levers.

3. A brooder having, in combination with a canopy, an elongated housing having one end terminating beneath the canopy and the other end projecting therefrom, an oil reservoir supported on the outer end of the housing, a burner located beneath the canopy, an oil supply pipe depending into the housing and extending through the housing for connection with the oil reservoir, and means for raising and lowering the burner including an operating lever mounted on the outer end of the housing, a second lever mounted at the inner end of the housing beneath the burner and operatively connected therewith, and means enclosed within the housing for operatively connecting said levers comprising a pair of bell-crank'levers respectively connected to the first mentioned levers and a link connecting said bell-crank levers.

4:. A. brooder having, in combination with a canopy, an elongated housi having one end terminating beneath the canopy and the other end PIOJQCtiIlg therefrom, an oil reservoir supported on the outer end of the housing, a burner located beneath the canopy, an oil supply pipe depending into the housing and extending through the housing for connection with the oil reservoir, and means for raising and lowering the burner including an operating'lever. mounted on the outer end of the housing, a second lever mounted at the inner end of the housing beneath the burner and operatively connected therewith, and means enclosed within the housing for operatively connecting said levers.

In testimony whereof, I have hereunto affixed my signature.
